Measuring efflux and permeability in mycobacteria

  • Autores: Ainsa JA, Rodrigues L, Viveiros M
  • Ano de Publicação: 2015
  • Journal: Methods in molecular biology
  • Link: http://www.ncbi.nlm.nih.gov/pubmed/25779319

The intrinsic resistance of mycobacteria to most antimicrobial agents is mainly attributed to the synergy between their relatively impermeable cell wall and efflux systems. The mycobacterial cell wall is rich in lipids and polysaccharides making a compact envelope that limits drug uptake.

Direct detection of Theileria annulata in bovine blood samples using standard and isothermal DNA amplification approaches

  • Autores: Gomes J, Inacio J
  • Ano de Publicação: 2015
  • Journal: Methods in molecular biology
  • Link: http://www.ncbi.nlm.nih.gov/pubmed/25399096

Tropical theileriosis is a tick-borne disease responsible for important health problems in cattle, caused by the hemoprotozoan Theileria annulata. Traditionally, detection of Theileria pathogens in infected animals requires the microscopic examination of stained-blood smears and serological methods.

Overview and challenges of molecular technologies in the veterinary microbiology laboratory

  • Autores: Cunha MV, Inacio J
  • Ano de Publicação: 2015
  • Journal: Methods in molecular biology
  • Link: http://www.ncbi.nlm.nih.gov/pubmed/25399084

Terrestrial, aquatic, and aerial animals, either domestic or wild, humans, and plants all face similar health threats caused by infectious agents. Multifaceted anthropic pressure caused by an increasingly growing and resource-demanding human population has affected biodiversity at all scales, from the DNA molecule to the pathogen, to the ecosystem level, leading to species declines and extinctions and, also, to host-pathogen coevolution processes.

Nested and Multiplex Real-Time PCR Using Dual-Labeled Probes: Detecting and Discriminating Mycobacterium tuberculosis Complex Members in Cultures and Animal Tissues

  • Autores: Costa P, Couto I, Inacio J, Viveiros M
  • Ano de Publicação: 2015
  • Journal: Methods in molecular biology
  • Link: http://www.ncbi.nlm.nih.gov/pubmed/25399092

Members of the Mycobacterium tuberculosis complex (MTC) are causative agents of tuberculosis (TB) in both humans and animals. In the last two decades, the accumulating knowledge of the nucleotide sequences of several genes, and of the whole genomes, of MTC members has allowed the development of novel molecular assays able to detect and discriminate between these species.

Fluorimetric Methods for Analysis of Permeability, Drug Transport Kinetics, and Inhibition of the ABCB1 Membrane Transporter

  • Autores: Ana Armada, António Sebastião Rodrigues, Célia Martins, Gabriella Spengler, Joseph Molnar, Leonard Amaral, Miguel Viveiros
  • Ano de Publicação: 2016
  • Journal: Methods in molecular biology
  • Link: http://link.springer.com/protocol/10.1007%2F978-1-4939-3347-1_7

The cell membrane P-glycoprotein (P-gp; MDR1, ABCB1) is an energy-dependent efflux pump that belongs to the ATP-binding cassette (ABC) family of transporters, and has been associated with drug resistance in eukaryotic cells. Multidrug resistance (MDR) is related to an increased expression and function of the ABCB1 (P-gp) efflux pump that often causes chemotherapeutic failure in cancer.
